I've taken logs to lams many times. If you have a 14" bandsaw with a 1 hp motor you can do most of the work at home. A tablesaw is useful as well.
It needs to be cut into lumber form so that it will dry evenly from all four sides to minimize warping. The ends should be sealed with shellac or something suitable.
I try to envision how slightly oversized 1 x 2's, 2 x 2's, 2 x 4's or whatever are hiding inside each piece relative to the growth rings... whether I'll strive for quarter or flat sawn depends on what the piece offers mostly, and then on my wants and needs.
I use a hefty 3/4" blade and get it right on the bandsaw and first try to attain a large flat side to use as a base for following cuts. Then begin removing waste while keeping succeeding cuts parallel or perpendicular to the first. There will be considerable waste, especially in that piece pictured above since it isn't exceptionally straight.
Once you turn it into a piece or pieces that resemble lumber, you can sticker it and allow it to dry. Once adequately dry, you can either continue toward making your own lams by precisely
squaring it up and resawing roughcut lams and grinding them... or stop at any point along the way and send them to someone with the capabilities and equipment to do so.
I used to get mine to the rough, oversized lam stage and then send them to Old Master Crafters, but now I have the equipment to do it all myself.
If you like, you could remove the excess waste and then when the time comes, after they're reduced and dry, I could resaw and grind them for you. That stuff would look beautiful under clear glass.
